Abstract：

The purpose of this study is to understand the role of practice teaching and its con-crete effects on the teacher preparation. This study is focused on the purpose of assess-ing the effect of using videotapes and peer feedbacks on the preservice chemistry teach-ers, in terms of their teaching abilities and self-evaluation. The subjects for this study includ 97 junior and senior college students, who participated in 297 classes of practice teaching.
The main findings of this research are as follows:(l) Practice teaching is significantly effective in improving preservice chemistry teachers' techniques in controlling their teaching processes; in application of their evaluation skills; and in using of teaching supplement; and (2) Videotape and peer feedbacks are useful for at least 50 % of the preservice chemistry teachers in their abilities of self-evaluation.
